can i use a harness and ecu from an si without modding my std.. or is it just as simple to mod and cheaper. and what else would i need for a sohc zc motor to fit in my std..

 

it is easier to drop in an obd0 dual cam zc motor. use an 88-89 integra ecu, and your stock wiring harness.

 

dont; use the pg7 ecu chip your pm6 to pm7 pg7 is gay

 

ok a little simpler for me.. im new to the swaping of ecus and all that... i just need a swap b/c my motor just went out last week.. but i just have enough for the sohc.. but any more suggestions

 

So like nobody is going to mention the fact he has to convert to MPFI?? and The Si harness will not plug and play with your STD harness.

Maybe some more people with more info can actually help..not like the other 2.

You'll need:

DPFI-MPFI conversion (easy, many instructions on it. Check the above website for DX to ZC wiring, its the same thing)

Si Harness (Or the one that comes on your motor, you just need some of the plugs)

A PM6 out of a Si will work, PM7 is from a DOHC ZC. They'll run about a hundred dollars each.

Um yeah, thats it. Its a shorter list than I thought.

DPFI to MPFI made simple

ECU: PM7 or a PG7 (89 teg)
Dont run the PM6 (sohc) with a DOHC ZC.

"Not that there's anything wrong with that."

 

yes you can use an SI harness, its not nessisarly plug and play, the wiring is actually quite complecated, more so than it looks in all those step by step articles... i just did a zc swap and my friend that always wires the ones i do came and did it. took him 3 hours, and he has done over 20 of them...

anywayan si ecu will work, but a pm7 will be a little peppier

you have to convert to MPFI from DPFI and to do this you have to have a resistor box and injector plugs/wiring

i recommend changing the timing belt and water pump when the motor gets to your house its easier than doing it later on down the road or in the car... good luck keep us updated

 

search before asking a stupid question.

nice.. thanks for the sa answer.. im tryin to make sense of the zc swap.. and the way i ask question are different than anyone else might ... but i got some more to ask.. so a si ecu will work but the teg is better.. i dont know the codes of them to well.. im a noob on motor swap.. so get a dx harness and convert it other than si.. and where id the best place to get a zc.. im goin with the sohc other than the dohc..

 

yes you can use the stock harness, and yes you can use an si ecu
